KSZ8873MLLJ Ethernet Switches

Integrated 3-Port 10/100 managed switch with two MACs MII or RMII interfaces

Image of Micrel's KSZ8873MLLJ Ethernet SwitchesMicrochip's KSZ8873MLLJ is the industrial version of the KSZ8873MLL that operates over the extended temperature range of -40°C to +125°C. It is a highly integrated 3-port switch on a chip IC. Low power consumption, advanced power management and QoS features enable a new generation of low port count, cost-sensitive and power efficient 10/100 Mbps switch systems.

Features

  • Advanced switch features
    • Tail tag mode (1 byte added before FCS) support at port 3 to inform the processor which ingress port receives the packet and its priority
    • MAC MII interface supports both MAC mode and PHY mode
  • Comprehensive configuration register access
    • Serial management interface (MDC/MDIO) to all PHYs registers and SMI interface (MDC/MDIO) to all registers
    • High-speed SPI (up to 25 MHz) and I2C master Interface to all internal registers
  • QoS/CoS packet prioritization support
  • Switch monitoring features
    • MIB counters for fully-compliant statistics gathering 34 MIB counters per port
    • Loop-back support for remote diagnostic of failure
  • Low-power dissipation
    • Full-chip hardware/software power-down and per port software power down
    • Energy-detect mode support
    • Per port based software power-save on PHY (idle link detection, register configuration preserved)
